Application led May 5, 1910. Serial No. 559,639.

To all whom it may concern:

.lle itt/known that MICHAEL C. SHEA, a citizen of the United States, residing at Mishawaka, in tlie county oli St. Joseph and State of indiana, have invented a new and useful lVheel: and I dolliercby declare the following to be a. full, clear', and exact description of the invention, such as will enable others skilled in the art to which it apper tains to make and use the same.

This invention pertains to a new and useful wheel, and the principle in View, is to provide a wheel havingg,V two rims spaced apart, intermediate of which a resiliently mounted rim is arranged, which intermediate rim moves with the hub and spokes of the wheel, for instance, when pressure is applied upon the hub, the intermediate rim yields incident to the applied pressure.

A further feature oi the invention is the production ot" a novel structure, for` conneeting` the spokes of the wheelto the hub. This hub comprises .a band having disposed upon its inner circumference twd rings spaced apart by meansv of the nuts carried by the spokes, and with which rings .plates engage. These plates are held in placeby the bushingr and the nuts,a shown in'the 'drawm The resilient meansy which v.is disposed upon each side .of the intermediate rinnand betweenA the innelr and. opter rims, maybe I made of solid rubber, or in the form eta pneumatic tube, it being' understood,l however.v that springs` may beai'ranged in place of the solid rubber or pneumatic tube. f This wheel may be constructed for use as atractiou wheel upon a traction engine, orl upon a locomotive, as shown yin the drawings. The wheel may also be made applicable upon an automobile, or any other vehicle.

ln the drawings, a certain form of device is disclosed, but in experimenting and reduc lue' to practice this form of device, if the applicant finds it necessary to alter various parts thereof, for instance, the details ot' the structure, he is entitled to do so, provided the alterations fall within the scope ot the ap pcnded claims.

In the drawings Figure 1 is a perspective view of a wheel embodying the features of the invention, and showin the wheel in the form of a traction whee lig.y 2 is a sectional view through the wheel to show the interior structure. Fig. 3 is u crosssectional View through afwheei sii-owing the andaJ nut 12 and outer rim in a contour Corresponding to a locomotive wheel. Fig. 4 is a sectional view through av portion of the wheel, show ingl pneumatic tubes in place of the solid rubber, and further disclosing` a rubber tire carried bythe outer rim oit the wheel, in order that. the wheel may be applicable to an automobile. f f

Referring to the annexed drawings, 1 de notes the'hub of the wheel, which consists of an annular band 2, on the inner circumference oi' Which two annular collars or rings 3 are disposed. These. rings or collars are held spaced apart by means of the nuts 4, which arethreaded upon theinner ends of the spokes 5. These spokes are threaded into the annular band. Also fitted within the annular band, from each side thereof, and in order to engage the collars or rings are annular plates G. These annular plates 6 are apertured as shown at 7, and extending throughl the apertures (whichare in regissleeve at one end is provided with a headportion 11, and to the other end a washer 13 are threaded. Also threaded to the end of the bushing or sleeve isa lock nutJ 14, in order to hold the parts securely together. ln each. of the. various forms ot wheels, asV shown in the drawings, the structure of the hub is identical.

15 denotes a resiliently mounted rim or' band," to 'which the free ends ofthe spokes are connected','by means of the nuts 16 and the shoulders 17. This rim or band is disposed between an inner and outer rim or band 1S and 19, Adjacent to the inner and outer faces of the rim 15, solid rubber bands 19 and 20 are disposed, there being one pneumatic tube 19h, shown in substitute for the solid 'rubber band 19. These solid rubber bands or pneumatic tubesl are arranged between the inner and outer rims, as shown,

in order to give or yield, incident to the presapertures which are designed to register These srings Q5, at intervals, are aise provided wltlr band l5, and the inner annular baud 19a is lerranged an annular band 30. This band 30 bears against the inner circumference of the solid rubber band 20. Between the annular band 30 (which is provided with elongated apertures 31 similar to the apertures `or openings JS) und the inner band 19a are dust guard plates These plates 3Q cover vthe registering end portions of the elongated apertures 3l and 2S, in order to prevent dust and other foreign matter from entering the innerband i921. These plates tit snugly about the spokes 5, in order that when the spel-:es nieve, they Will move with them, thereby continually covering the registering elongated apertures 3l and 28.

The invention having been described, what isclanned as new and useful is l. in. a wheel, the combination of an inner and outer iini, of a resiliently mounted intermediate rini, an annular band surrounding the inner riin, said annular band and iniier rini having registered elongated apertures, designed to receive the spokes, said 'Upon examining the draw-- y spokes,

spokes being secured to the resiliently rmounted intermediate riin and plates movable with the spokes and arranged between the annular bend and the inner rim.

2. In e Wheel, the combination of inner and outer rims having annular flanges provided Wit-h apertures, of annular rings having apertures in registration With the first named apertures, screws penetrating the registering apertures, said inner riin having elongated openings, an annular band surrounding the inner rim between it-s flanges and provided with elongated openings in registration with the first named opening, an annular rim arrtinged intermediate the outer rini and the annular bend, resilient ineans located on each face of the intermediate riin to cooperate between it and the outer rim and the annular band, in combination with spokes penetrating the seid elongated openings and having restricted threaded ends penetrating the intermediate rim, nuts threaded to the restricted ends of the und plates erranoed between the inner rim and the annular band to cover the registering elongated openings, and through which the spokes are vertically movable, said'plates being movable with the spokes when the spokes are not moving vertically through them. l

In testimony whereof I have signed my naine to this specitication in tlie presence of tivo subscribing Witnesses.
